"This alarm is a replacement for a previous alarm supplied by BG, after five years of service.This alarm is small and compact and a great value item and was less than half the cost of the original, although what price do you put on a safety item such as this.on installation after fitting rechargable battery alarm was up and running afterno time at all, so easy and on testing this was loud enough to wake anyone."

"I have used many First Alert productsand always find them reliable and easy to fit. I bought two of these, at a bargain price from Screwfix, to go into motorhomes for customers. Simple, easy to fit and look smart - fit and forget!"

"I wanted a carbon monoxide alarm for my caravan. This model does need to have its batteries changed every year, but that it no problem to me as I'll do this as part of the caravan 'set-up' at the start of each season."

"did what it said on the tin!!! works out the box, fit batteries (supplied), insert fixing screws and 'hook' ononly gave it 3 for performance and reliability as just fitted it - it may last the 7 years stated on the packaging - untill then reliability ???? it does state a 5 year guarantee so we will see!!!

"This is the second one of these I have purchased - the first is in our utility room with the gas boiler and has been working perfectly now for 2 years on the original batteries (I test it every month just to be sure).This one is for a new wood burning stove we've installed.At the price and reliability, it makes sense to have one for any situation where CO poisoning could occur. Why take the risk?"
